Abstract: GENERATION OF TOPOLOGICALLY PROTECTED SOLITONS IN OPTICAL FIBER We present a topologically protected optical fiber that eases topologically protected soliton propagation. The fiber is made up of two photonic lattice sections with discrete topological phases that create an interface to support a confined, protected, robust edge mode. An optical pulse sent via the interface mode undergoes nonlinear evolution to generate a temporal soliton through the interplay between chromatic dispersion and self-phase modulation. Due to the topological nature of the guiding mode, the resulting soliton is more resistant to structural flaws and disorder vis-à-vis conventional single-mode fiber. The invention sets up a foundation for stable nonlinear optical transmission and future secure communication systems, including quantum communication.
